DD MEASUREMENT TAKEN WITH ALL INSTRUCTIONS EXECUTING FROM
INTERNAL MEMORY. 50% OF THE INSTRUCTIONS ARE MULTIFUNCTION
(TYPES 1, 4, 5, 12, 13, 14), 30% ARE TYPE 2 AND TYPE 6, AND 20% ARE
IDLE INSTRUCTIONS.
4 IDLE REFERS TO ADSP-2189M STATE OF OPERATION DURING EXECUTION
OF IDLE INSTRUCTION. DEASSERTED PINS ARE DRIVEN TO EITHER VDD
OR GND.
